window-management

I've been contemplating making a window manager with a GUI, probably in Java. However, I'm struggling to figure out the best way to move windows not owned by my program. So far, it would seem I should use JNI to interface with the Windows API, but I haven't found any helpful examples. Does anyone know how to do this? Thanks! PS. I'm not necessarily tied to Java, if there is a better language to do this in. If the purpose is to have a fast window manager you are certainly better off with C++ or C#, or maybe even Delphi. But if you are most familiar with Java it can be done. If you choose the

I'm a bit confused with some gtk and gnome concepts. I'm trying to get list of non minimized windows on my gnome2 desktop, but after reading the pygtk documentation and inspecting the results, I can't understand the results. Neither of the two snippets below appears to work. First I tried this.. >>> gtk.gdk.window_get_toplevels() [<gtk.gdk.Window object at 0xb74339b4 (GdkWindow at 0x8a4c170)>] >>> gtk.gdk.window_get_toplevels()[0].get_children() [] then this >>> d = gtk.gdk.DisplayManager() >>> d.get_default_display().get_screen(0).get_root_window().get_children() [<gtk.gdk.Window object at

I want to create a simple stacking window manager (in C ) for private use, mainly for the purpose of learning and challenging myself. I've looked through twm 's source code which has relatively few bells and whistles but it seems very low level since it's not based on a widget toolkit. 1 Would using a toolkit such as GTK+ be preferable? I'm afraid that some of the code and libraries in twm might be too antiquated ( edit: deprecated) and I want the window manager to use relatively modern libraries. For the sake of understanding I would also be interested in suggestions how to start a window

I have a small python script which draws some turtle graphics. When my script has finished running, the turtle screen automatically closes, so to be able to see the graphics for a while I have to use time.sleep(5) at the end of the script to delay the closing. Is there any way I can make this more dynamic, i.e. tell python that I want to control the closing of the window myself? I don't mind if the script can't do anything else while waiting for my command, but I'd prefer if I didn't have to go to the console for a read() or something. Ideally, the canvas should stay open even after the script

I'm using the Qt library to show a slideshow on the second monitor when the user isn't using the second monitor. An example is the user playing a game in the first monitor and showing the slideshow in the second monitor. The problem is that when I open a new window in Qt, it automatically steals the focus from the previous application. Is there any way to prevent this from happening? dutchmega It took me a while to find it but I found it: setAttribute(Qt::WA_ShowWithoutActivating); This forces the window not to activate. Even with the Qt::WindowStaysOnTopHint flag If you want to make floating

Is there a way to tell Matlab not to steal window focus (from an external editor) such as Emacs) upon graphical commands such as figure and plot . This would increase my productivity a lot because I often want to continue code development during data (re-)processing. It is possible, the trick is to not use the figure statement, but to change the current figure directly. This will change the active plot without changing the focus. Typically I do something like this: function change_current_figure(h) set(0,'CurrentFigure',h) Then, all of the figure(h) statements need to be changed to change
